very confused

So me And my babydaddy have been together going on 3 years now recently when I was 39 weeks pregnant he decided that we need a break due to us always arguing and asked me to move out it was a lot on me to have to accept what was happening but I tryed to be strong for me and our daughter for the last to weeks of my pregnancy I was trying to figure out what went wrong I was giveing him his space that he need for him to only call me in the middle of the night begging for me to call him or because he was thinking about me I would go days without answering his calls but he would still call and text and get mad that I had his number blocked and he felt I was ignored him .finally after 24 hours I gave birth to our baby girl that's were it was getting weirder he would act as if we were together on day and then the next we weren't .he started a random fight and he told me how I've been lying to him and that I have 2 facebooks how I have a new boyfriend and how he feels pushed away from me because I'm not up his ass or even allow him to call and have a conversation with me that don't pertain to our baby I feel like he wants me but wants to be single too I need to let him go but is makeing it so difficult by playing mind games
